Abstract

The invention discloses epoxy anticorrosive paint for a circuit board. The epoxy anticorrosive paint is characterized by being prepared from the following raw materials in parts by weight: 80-85 parts of E-12 epoxy resin, 3-4 parts of aluminum powder, 1.4-1.6 parts of hexamethylene tetramine, 2-3 parts of triethyl acetyl citrate, 5-7 parts of talcum powder, 1-2 parts of an antioxidant DSTP (disteaxylthiodipropionate), 3-4 parts of vinyl tri(beta-methoxyl ethyoxyl) silane, 2-3 parts of isopropanol, 15-20 parts of ethyl acetate, 1-2 parts of zinc cyanurate, 3-4 parts of zinc oxide, 12-15 parts of bauxite, 2-3 parts of isocyanate and 3-4 parts of a dispersing auxiliary. The dispersing auxiliary improves the optical property, so that the paint is uniformly dispersed, and the stability of the paint is maintained. The gasoline and machine oil wiping resistant epoxy anticorrosive paint is mainly applied to metal surfaces and advertising boards, has excellent anticorrosive property, adhesive force, hardness, shock resistance and covering power, and is free from color fading.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a circuit board epoxy anticorrosion paint and a preparation method thereof. Background technique [0002] The names of circuit boards are: circuit board, PCB board, aluminum substrate, high frequency board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Because the circuit board works in various environments, many of which are harsh, such as light, high temperature, and corrosion, it is necessary to coat the circuit board with paint for protection, and the existing paint cannot meet this requirement. [0003] Contents of the invention [0004] The purpose of the present invention is to provide a kind of circuit board epoxy ...
